Abstract

The present invention relates to a method for the continuous preparation of high bulk density methionine crystals. The process of the method is as follows: a hydrolysate, which is obtained from a reaction of 5- (P-methylthioethyl)hydantoin and a potassium carbonate solution, is mixed with an external circulation material from a OTB neutralization crystallizer having a gas phase neutralization section; after the mixture is cooled, the mixture enters a liquid distributor of a neutralization region in the upper part of the crystallizer; the mixture is sprayed in liquid droplet or trickle into carbon dioxide gas for neutralization reaction, and then naturally falls into a crystallization region in the lower part to be mixed with a material in the region; the mixture grows on small crystals in a system to form crystals having larger particle diameters, and meanwhile new crystal nucleuses are formed; in a settling region in the middle part of the crystallization region, the crystals having larger particle diameters sink into an elutriation leg, while the small crystals circulate with the external circulation material, and a part of the external circulation material is used for elutriating the crystals in the elutriation leg, and another part of the same is used for mixing with the hydrolysate; and the crystals in the clutriation leg are separated, washed and dried to obtain the high bulk density methionine product.
